Mozilla Firefox OS for Smartphones in India

Firefox OS is designed to provide a complete community-based alternative system for mobile devices, using open standards and approaches such as HTML5 applications, JavaScript, a robust privilege model, open web APIs to communicate directly with cellphone hardware, and application marketplace. As such, it competes with commercially developed operating systems such as Apple's iOS, Google's Android, Microsoft's Windows Phone and Jolla's Sailfish OS as well as other community-based open source systems such as Ubuntu Touch.

Most smartphones found in the market these days are made by a small number of individuals, all in one place. However, Firefox OS mobile phones are very different. They are made by a huge global community, and they are the only smartphones that know and provide what users need and want. It delivers all the necessary information you want including not only famous, big name applications but also local contents that are valuable to you and to your life. In addition, Firefox OS is loaded with exceptional features that you will love with a smartphone.

Firefox OS features an Adaptive App Search that allows users to type a word or even a subject they are interested in, save apps to their phone, get instant access to the applications they need, find exactly what they want and discover more applications on Firefox Marketplace.
The developers of this new operating system are seeking to make a difference in the world, and not merely a profit. By choosing Firefox OS, users are also playing a big role in establishing a brighter future for the World Wide Web as well as users everywhere.

Firefox has always been changing the browsing experience of people and providing a whole new level of innovation online. With the inception of Firefox OS, they  are doing it again by changing their browsing experience to their smartphones. This allows them to take control of their life wherever they may go.
Currently, Intex, Spice and Alcatel are selling Firefox OS-based smartphones in India. The cheapest Firefox-powered handset costs Rs. 1,900.
